Data Delving


When you’re drafting an email, ending it is the easiest part. Whether you sign-off with “Warmest Regards,” “Thanks,” or “Keep On Keepin’ On,” it only takes a second, and you probably don’t give it a second thought. Do email closings even matter? And if so, is “best” really best? We looked at closings in over 350,000 email threads, and found that certain email closings deliver higher response rates.

Your Monday morning alarm might be the worst sound in the world. Weekends fly by, but Mondays drag on forever. As avid Office Space fans, we wondered if having a “case of the Mondays” was an observable phenomenon. Our finding? Monday really is the worst day of the week: it’s when people make the most mistakes in their email subjects (which, as we will show, matters), as well as the day with the most negative email subjects. Subject...

Word of mouth recommendations are among the most effective ways to get new users. But they can be an elusive element of a marketing mix. Aye Moah (our Chief of Product) wrote a piece a few years ago on how Boomerang uses the paywall to have a positive interaction with users. But we also use it to encourage customers to tweet about Boomerang in exchange for more message credits (which allow users to snooze or schedule emails for...

We had our Geico moment here at Boomerang last week, discovering that 5 minutes could improve Android app install rates by 15% or more (for us, it was more). When we added bold and underline formatting to our app’s existing Play Store description, our install rate increased significantly, even as we kept the copy, images, and everything else identical. Though it’s not well-publicized, Android app descriptions support rich formatting...

Over the past year, our customers asked Boomerang to remind them if they didn’t get a response to over 40 million emails. Writing emails that get responses is an incredibly valuable skill – and what makes an email likely to get a response is hard to determine.

There’s a lot of advice about how to write a good email on the web, from general writing advice to full sets of pre-written email templates. But almost none of that advice shows the data behind it (usually because there isn’t any), and a lot of it is contradictory.

So when we set out to send out a year-in-review email (yes, this was supposed to go out early in January, but we hit the lunar new year instead – happy Year of the Monkey!) to Boomerang users, we decided to make that email different from a typical startup year-in-review email. Instead of focusing how much we’ve grown* or showing off our swanky new logo**, we decided to figure out what factors really matter when you want to get a response to your messages and send that instead.

The 2016 presidential race has given us Trump, Bernie, and most excitingly (if you’re an email geek) a plethora of emails to and from Hillary Clinton and Jeb Bush. The State Department has published scans of thousands of pages of Hillary’s emails from a private server she used during her tenure as Secretary of State. Jeb Bush, meanwhile, self-released over 280,000 emails from his time as Florida Governor on jebemails.com While some...
